Belt-Couplings, of which thefollowing is a specification.

My invention relates to belt couplings, and more particularly to hingedor pivoted couplings, the object of the invention being a plan view ofthe outer toprovide a coupling of this character, of simpleconstruction, which can be easily stamped from sheet metal and bereadily adjufilted to the width of the belt, and which w withstand allstrains and stresses thereon.

in the accompanying drawings Figure 1 is face of a belt with one form ofmy coupling ap lied thereto. Fig. 2, is an edge view of the eltcoupling. Fig. 3, is a perspective view of the coacting couplingmembers. Fig. 4, is a perspective view or a modification. Fig. 5, is aplan view of a modification, and Fig. 6, is a perspective of anothermodification.

Referring to Figs. 1, 2 and 3, B, B designate the body portions of twoseparate coupling members adapted to be applied to the ody portion sameend of a belt A. Each has projecting from it the downwardly and inwardlyturned sleeve F1, or b" formed by rolling an extension of the bodyport-ion blank around a. mandrel. It is to be particu larly noted thatthe sleeve portion is narrower than the body portion, that the twosleeves project downward between the edges .of the ends oi the belt, andthat the two elements on the same end of the coupling I in. regard totheir belt are -op ositely placed sleeves, bot i of the sleeves beingtoward the margins of the belt as shown in Fig. 1. This arrangementgives greater strength in resist ing lateral strains than if two likesections'of couplings were arranged with the sleeves on the same side,as in this latter case any side wise strain would not be resisted saveby the overturned head of the pintle D. With my construction the lateralstrain in either di- I U rection 1s resisted by theends of the sleevewhere they abut against each other, as well as by the intle itself. 0, Cdesignates the members having have sufficient longitudinal strength to'Wardly turned sleeves c, e oppositely disposed to the sleeves b, b, andso arranged r latively to each other that the-sleeves 0, e shall belocated interiorlyor between the sleeves I), b. D designates thepintles, one for each coupling having headed ends to prevent theiraccidental withdrawal.

1' have shownin Fig. 6, a modified form of coupling member which willhold the pins in place without the-necessity of their. being headed, andwhich will'permit the easy withdrawal of the pintles when desired. ThisB? with a lateral extension or ear B adapted to be downwardly turnedagainstthe end of the sleeve after the pintle is in place. When it isdesired to removethepintle, this extenf sion orear B is turned up oneach of the coupling members, and the pintle pushed out, thusdisengaging the two ends of the belt. This feature is also shown in Fig.4.

' It is to be noted that I provide a plurality of rivet holes E, onelocated behind the other for the rivets F. This permits the couplingmember to be reset longitudinally on the belt to take up slack, withdutthe necessity of making new-rivet holes 'in the belt and therebyweakening it. Instead of the holeslmay use the lateral extended recessesE as shown inFig. 5.

In Fig. 4, I show a modified formcl coup ler wherein the two bodyportions B, B are connected at the extremities by-a cross bar B. Thisacts to give a better. engagement with the belt, while not preventingthe belt and its coupling yielding to laterahliexing, for the reasonthat the metal betyvpen the two body portions, B, B is cut away and"thus the two arms so formed are, to a degree, elastically supportedrelatively to the cross bar B, so as to havea movement at right anglesto the plane of the belt, independent of each cross bar C is constrdctedin -the same manner as shown in Fig. 5. 'It is to be noted, that thecross bar may be'provided with rivet inodification consists informingthe sleeve other. The coacting member C, C with its roe hole bwhereby the cross bar may be fas- 7 4'0 'i mit the belt to flexlaterally as it'should. It

rection, thu permittin the coupling memher to be shifted lateral y upona slight loosening of the rivet and this will allow the coupling memberto be removed very easil I vide fora freedom of lateral movement orflexing, which is impossible with-belts having wide bodied hingesextending across a large portion of the belt, or those wherein a phirality of short inter;engaging sleeves are used,- the sleeves ofopposite members inserted be tween and contactin with each other. Byjoining the separate odiesof the couplings by the cross bar, I secure abetterattachment to the belt, while leaving theseparate coup: lingmembers on the same side free to have independent movement, and avoidany chance of lateral stifi'ening or rigidity. Y The plurality of rivetholes permit the couplings to be adjustedso as to take up the slack ofthe belt, and the modified form shown in Fig. 6 will ermit'thepintles tobe removed easily and -Wlll hold the pintles securely in position whilein operation.

I am aware t'hat hinged couplings have been heretofore devised, andthese are not within the, spirit of my invention. Such. hinges stiffenthe end of the belt too much, particularly in narrow belts and do notperwill beseen that in myv invention narrow belts are not rigidlyconnected across their entire width, but only at points along the Widthof the belt, and that in all the embodiments which I have illustratedthese separate hinge connections are practically inde pendent ofeachother as far as lateral flexing goes.

Having thus described my invention what claim as new and desire tosecure by Letters Patent is: Y

1; in combination with two adjacent ends of a belt, arallel memberssecured to the face of the be t at both ends of the belt, and theopposite members of each pair located in alinement, downwardlyprojecting sleeves on all of said members at the ends of the belt, allof said sleeves in alinement, and

both sleeves of the pair of members on one belt end located nearer thecenter of the belt, than are the sleeves of the other pair of membersand the sleeves of one pair of members located against the sleeves ofthe other pair of members, and coupling pins in the adjacent sleeves ofsaid members. 1

- 2. A coupling for belts comprising two members, each member having abody por tion and a single downwardly projecting sleeve narrower thanthe'body portion, said I sleeveha'ving at its outer end a downwardlyextending ear covering the open end of the sleeve, and a pintle adaptedto pass through both sleeves and to be held therein by the downwardlyprojecting ears on the sleeves.

8. In comblnation with two adjacent ends of a belt, parallel memberssecured to the face of the belt at .both ends thereof, and the oppositemembers of .each'pair located inaline- I ment, downwardly rejectingsleeves on all of said members at t. e ends of the belt, all of saidsleeves in alinement, coupling pins in the adjacent ends of the pairs ofsleeves and downwardly projecting ears on oneof said pairs of memberscovering the openings in the ends of" the sleeves and projecting overthe end of the cou ling pins.

In testimony w ereof I have signed my name to this specification in thepresence of two subscribing Witnesses. 1
